This page will help you get to the bottom of card payment machines and get you ready to start taking card payments today.

How does a PDQ machine work?

Once a customer has tapped the machine, or inserted their card into the slot and entered their PIN, the machine authorises the payment (provided there are sufficient funds in the customer’s account), and sends the payment to your merchant account.

Once the payment is received from the card-issuing bank, the funds will be transferred to your business bank account.

• Mobile – a small, portable device that uses mobile data to take card payments on the go

Different types of PDQ machines suit different types of businesses. Though your business may have a variety of card machines in order to have a more comprehensive payments setup.

PDQ machine costs

PDQ machines are available to rent or buy from any major payment processing or merchant services provider.

Depending on type, the devices themselves can cost anything from £15 to upwards of £150. Though with countertop and portable devices, it’s most common to rent them for between £15 to £25 a month.

While we’ll be looking at devices, it’s important to understand that PDQ device costs don’t exist in a vacuum. If you’re buying a device from a particular card machine company, you’ll also be using their payment processing services – it’s all one package. That means being subjected to any monthly fees and transaction costs.

These ongoing costs vary from provider to provider, so it’s worth hunting around for a fee structure and pricing model that works for your business.
